From an internal standpoint, the A5 is already old news within the company. I'm sure Apples engineers are deep into the A6 project which will have quite a positive opportunity for the iOS team to build their software accordingly. There's so much more current & future potential in the A6 architecture, that will be the real news item for quite some time.
Also, some reports have the first stages of the planned iOS & OS X convergence being executed concurrently. It's this project that will finally reveal what the true vision Apple has in mind for their customers future.
Given the fact that only so much is required from a mobile OS for phones & pads, it's hard to imagine anything impressive when this single OS, and mobile chips are used in what used to be known as a laptop or desktop. Taking into consideration the latest rumor of all new devices from Apple sooner rather than later, if true, there will be big changes from the gadget company.
